Who were the nephilim? The word nephilim appears twice in the Old Testament of the Bible. They are first mentioned in chapter 6 of the book of Genesis and then again in Number 13:33. But their brief mention in the Bible has led to an ongoing debate as to who or what the nephilim were. Much of this debate stems from the passage in the Bible that states:
"When people began to multiply on the face of the ground, and daughters were born to them, the sons of God saw that they were fair; and they took wives for themselves of all that they chose. The Nephilim were on the earth in those days - and also afterward - when the sons of God went in to the daughters of man, who bore children to them. These were the heroes that were of old, warriors of renown." - Genisis 6: 1-4
The traditional definition of Nephilim is giant. Some dictionaries describe the nephilim as being giants who also possess super human strength. The Greek Septuagint, an ancient translation of the Hebrew Bible, refers to them as gigantes, which actually means "earth -born". It is believed by some scholars that the word Nephilim comes from the root word "Naphal" which means to fall.
